A paritally plane polarised bem of light is passed through a polaroid.Show graphically thervriation of the trnsmitted ligth intensity with angle of rotation of the polaroid.

Light from an ordianry source(say a sodium lamp) is passed through a polaroid sheet P_1 .The transmitted light is then made to pass through a second polaroid sheet P_2 ,which can be rotated so that the angle (theta) betwen the two polaroid sheets varies from 0^@ to 90^@ .Show graphically the variation of he intensity of light transmitted by P_1 and P_2 as a function of the angle theta .Take the incident beam intensity as I_0 . Why does the light from a cleear blue portion of the sky,show a rise and fall on intesnity,when viewed through a polaroid ,which is rotated?

A beam of unpolarised ligth is made to fall,from air ,on its boundary with another transparent medium of refrective index mu .The reflected beam is viewed through a rotating analyser.Show on a graph,the variation of intensity of light trasmitted through the analyser with the angel between the pass axis of the analyser and the direction of the reflected beam.

When a ray of light passes through a parallel slab of transport medium, then show that angle of incidence is equal to angle of emergence.

An unpolarised beam of light of intensity I_0 is incident on a combination of two polaroids.Find the net intesity of light of intensity transmitted by the combinatin,when the pass axis of the two polaroids are inclined to each other at an angle of 60^@ .

Two polaroids are set in corossed positions.A third polaroid is placed between the two making an angle theta with the pass axis of the first polaroid.Write the expession for the intensity of light trnasmitted from the second polaroid .In what orientations will the transmitted intenesity be minimum adn

Two polaroids are set in corossed positions.A third polaroid is placed between the two making an angle theta with the pass axis of the first polaroid.Write the expession for the intensity of light trnasmitted from the second polaroid .In what orientations will the transmitted intenesity be maximum.

Two polaroids are placed at 90^@ to each other and the transmitted intensity is zero .What happens,when one more polaroid is placed betwen these two,bisectiing the angle between them.How will the intensity of transmitted light vary on further rotatint the third polaroid?

If the angle between the pass axis of a polariser and the analyser is 45^@ ,write the ratio off the intensitties of original light and the transmitted ligth after pasing through the analyser.

Two polarised are placed at 90^@ to each other and the intensity of transmitted light is zero. What will be the intensity of transmitted light, when one or more polaroids is placed between these two bisecting the angle between them? Take intensity of unpolarised light as I_0 ?
